There is a problem with your OBC. Brand new batteries will often go 16 hours and trip the time limit as they have not had a full charge, but if it does not cut off, there is definitely an issue.

If you check it with your volt meter, see where the charge is after several hours. Inherently the DC amps will drop because you are fully charged, but when you see ~62-63 volts and low amps for a sustained amount of time, you need to unplug it from the wall as it is not working correctly as proven by it not timing out.

If it has failed, which it appears yours has, you do not want to use it for long as it is not properly use the charge algorithm and can damage your pack over time.

Time to look at another OBC (some get sold here in the Sale section) or better to completely bypass it start using a new smart or high frequency charger. (Summit II, Delta-Q, DPI, Yewey)

PS- One last test you can do is the cart should not move (activate the solenoid) while charging.
